Book SynopsisIn 2010, Richard Merrick took a family trip to Scotland''s Rosslyn chapel—the enigmatic fifteenth-century temple made famous by Dan Brown''s The Da Vinci Code. Little did he know he was about to embark upon an intellectual and personal journey that would lead to the discovery of a real-life lost symbol—one that reveals the connection between the world''s most sacred temples and opens up a treasure trove of lost science and ancient secrets. The symbol he discovers—the Venus Blueprint—is based on that planet''s orbital pattern, which takes the shape of a five-pointed star when seen from Earth. As Merrick digs deeper, he realizes the Venus Blueprint was an integral part of the design template of some of the most significant religious architecture around the world--including St. Peter''s Basilica in the Vatican, the Roman Pantheon, the Greek Parthenon, the Temple of Jerusalem, and the Great Pyramid of Giza, as well as many buildings designed by the secretive Freemason society. Upon further examination, Merrick is astounded to discover that temples designed using the Venus Blueprint are endowed with extraordinary acoustics that, when supplied with the right tones and frequencies, are capable of harmonizing with Earth''s resonant frequencies and evoking altered states of consciousness. He then proposes a fascinating idea: Could it be that the ancients used these harmonics to enhance entheogenically induced visions—to commune with the divine and liberate the gods within? Supported by an impressive array of historical research and scientific analysis, The Venus Blueprint offers compelling evidence of an ancient lost culture that was both spiritually and scientifically advanced.

Book SynopsisThis book explores light and other types of waves, using this as a window into other aspects of physics. It emphasizes a conceptual understanding, using examples chosen from everyday life and the natural environment. For example, it explains how hummingbird feathers create shimmering colors, how musical instruments produce sound, and how atoms stick together to form molecules. It provides a unique perspective on physics by emphasizing commonalities among different types of waves, including string waves, water waves, sound waves, light waves, the matter waves of quantum mechanics, and the gravitational waves of general relativity. This book is targeted toward college non-science majors, advanced high school students, and adults who are curious about our physical world. It assumes familiarity with algebra but no further mathematics and is classroom-ready with many worked examples, exercises, exploratory puzzles, and appendices to support students from a variety of backgrounds.Trade Review“‘Light and Waves’ fills a need to educate non-science majors and laypeople on the joy of optics. This highly recommended book inspires questions, curiosity, excitement and interest in the natural universe. … this book special is the quality of the questions, the variety of worked problems with answers, the numerous exercises and crucial additional resources.” (Barry R.

Book SynopsisAlthough the mathematical theory of nonlinear waves and solitons has made great progress, its applications to concrete physical problems are rather poor, especially when compared with the classical theory of linear dispersive waves and nonlinear fluid motion. The Whitham method, which describes the combining action of the dispersive and nonlinear effects as modulations of periodic waves, is not widely used by applied mathematicians and physicists, though it provides a direct and natural way to treat various problems in nonlinear wave theory. Therefore it is topical to describe recent developments of the Whitham theory in a clear and simple form suitable for applications in various branches of physics.This book develops the techniques of the theory of nonlinear periodic waves at elementary level and in great pedagogical detail. It provides an introduction to a Whitham's theory of modulation in a form suitable for applications. The exposition is based on a thorough analysis of representative examples taken from fluid mechanics, nonlinear optics and plasma physics rather than on the formulation and study of a mathematical theory. Much attention is paid to physical motivations of the mathematical methods developed in the book. The main applications considered include the theory of collisionless shock waves in dispersive systems and the nonlinear theory of soliton formation in modulationally unstable systems. Exercises are provided to amplify the discussion of important topics such as singular perturbation theory, Riemann invariants, the finite gap integration method, and Whitham equations and their solutions.Table of ContentsIntroduction and basic concepts; nonlinear wave equations in physics; Whitham theory of modulations; complete integrability of nonlinear wave equations; periodic solutions; dissipationless shock wave; nonlinear theory of modulational instability. Appendices: some formulas from the theory of elliptic functions; algebraic resolvents of fourth degree polynomials; solutions to exercises.

Book SynopsisAs a critical theoretical advance, Understanding Plane Waves discusses the acoustic Goos-Hänchen effect. The important applications of this effect are discussed, including plane wave propagating inside transversely isotropic elastic-solids, reflection/refraction at interface between two anisotropic rocks, and acoustical applications to petroleum logging and seismic exploration. Next, the authors explore a newly developed acoustic-measurement system with emphasis on measurement process and recent improvements that make an acoustic-measurement more accurate. Three approaches which are used to analyze the evolution of the plane longitudinal and transverse waves that are propagated in a nonlinear hyperelastic medium are discussed: the method of successive approximations, the method of slowly varying amplitudes and the method of restriction on the displacement gradient. Lastly, the subject of relativistic quantum particles interacting with classical plane wave fields is examined from the standpoint of space-time symmetries which have been found to be encoded in the solutions of relativistic equations.Table of ContentsPrefaceRecent Progress in Acoustical Theory and ApplicationsRecent Development of an Acoustic Measurement SystemPlane Nonlinear Elastic Waves: Approximate Approaches to Analysis of EvolutionSpacetime Symmetries and Interaction of Quantum Relativistic Particles with External Plane Wave FieldsIndex.

Book SynopsisAcoustics is the science concerned with the production, control, transmission, reception, and effects of sound. Its origins began with the study of mechanical vibrations and the radiation of these vibrations through mechanical waves, and still continue today. Research was done to look into the many aspects of the fundamental physical processes involved in waves and sound and into possible applications of these processes in modern life. The study of sound waves also leads to physical principles that can be applied to the study of all waves. The broad scope of acoustics as an area of interest and endeavour can be ascribed to a variety of reasons. First, there is the ubiquitous nature of mechanical radiation, generated by natural causes and by human activity. Then, there is the existence of the sensation of hearing, of the human vocal ability, of communication via sound, along with the variety of psychological influences sound has on those who hear it. Such areas as speech, music, sound recording and reproduction.

Book SynopsisWe think of noise as background sound that interferes with our ability to hear more interesting sounds. But noise is anything that interferes with the reception of signals of any sort. Whatever its cause, the consequence of noise is error by receivers, and these errors are the key to understanding how noise shapes the evolution of communication.Trade ReviewExtremely readable and thought-provoking… The result of all this erudition and stimulation is very likely the best book of science published by a mainstream press in 2015, something that will make readers think about every sound they hear and why they hear those sounds and why they prefer some of those sounds to others. It’s an invigorating inquiry. -- Steve Donoghue * Open Letters Monthly *Haven Wiley gives a superb overview of how communication has evolved. -- Hansjoerg Kunc, School of Biological Sciences, Queen’s University Belfast

Book SynopsisTraditionally heat and light are thought as energy sources to drive a particular chemical reaction, but now ultrasound is a promising energy source for this purpose. The collapse of a bubble generates a wide range of high temperatures and pressures, and therefore, use of ultrasound has a considerable potential in chemical and allied sciences. Ultrasound-assisted reactions are green and economically viable alternatives to conventional techniques. This new volume presents a complete picture of ultrasound-assisted reactions and technologies that can be used in organic synthesis, polymer synthesis and degradation, nanomaterials, wastewater treatment, food ingredients and products, pharmaceutical applications, bioenergy applications, and more. This volume aims to shed light on the diversified applications of ultrasound and its significant role as a green chemical pathway. Sonochemistry deals with the effect of ultrasonic waves on chemical systems. It has green value because of non-hazardous acoustic radiation and is therefore duly recognized as a green chemistry by synthetic chemists as well as environmentalists. There is no direct interaction of ultrasound with molecular species, but the observed chemical and physical effects of ultrasound are due to the cavitational collapse, which produces drastic conditions of temperature and pressure locally. It induces the formation of various chemical species, which cannot be easily attained under conventional conditions. Sometimes, these species are responsible for driving towards an unusual reactivity in molecular entities. This book, Sonochemistry: An Emerging Green Technology, provides the complete development of sonochemistry, starting with an introduction and basic concepts of sonochemistry and proceeding on to different types of sonochemical reactions, instrumentation, use of ultrasound in driving particular chemical reactions, and its applications in various fields, such as polymer synthesis, decontamination of water and wastewater, preparation of nanomaterials, food technology, pharmaceutical sciences, etc.The book also briefly discusses some areas that utilize ultrasounds of different frequencies. These include food products and their processing; anaerobic digestion of waste; and medical applications such as ultrasonography, sonodynamic therapy, drug delivery, etc. Sonochemistry will be successfully used on an industrial scale in pharmaceutical drugs, polymers, nanomaterials, food technology, material science, biogas production, etc. in years to come and will be an established green chemical technology of the future.Table of ContentsIntroduction.

Book SynopsisSince the publication of the first volume “Infrasound monitoring for atmospheric studies” published in 2010, significant advances were achieved in the fields of engineering, propagation modelling, and atmospheric remote sensing methods. The global infrasound network, which consists of the International Monitoring Network (IMS) for nuclear test ban verification completed by an increasing number of regional cluster arrays deployed around the globe, has evidenced an unprecedented potential for detecting, locating and characterizing various natural and man-made sources. In recent years, infrasound has evolved into a broad interdisciplinary field encompassing academic disciplines of geophysics and innovative technical and scientific developments. The advances in innovative ground-based instruments, including infrasound inversions for continuous observations of the stratosphere and mesosphere, provide useful insights into the geophysical source phenomenology and atmospheric processes involved. Systematic investigations into low-frequency infrasound signals and the development of complementary observational platforms point out new insights into the dynamics of the middle atmosphere which play a significant role in both tropospheric weather and climate. This monitoring system also provides continuous relevant information about natural hazards with high societal benefits, like on-going volcanic eruptions, surface earthquakes, meteorites or severe weather. With this new edition, researchers and students benefit from a comprehensive content of both fundamental and applied inter-disciplinary topics.Table of ContentsPart 1: Instrumentation, network and processing.- Chapter 1.The IMS Infrasound Network: Status and state-of-the-art design (Julien Mary).- Chapter 2.

Book SynopsisAn engineering-oriented introduction to wave propagation by an award-winning MIT professor, with highly accessible expositions and mathematical details—many classical but others not heretofore published.A wave is a traveling disturbance or oscillation—intentional or unintentional—that usually transfers energy without a net displacement of the medium in which the energy travels. Wave propagation is any of the means by which a wave travels. This book offers an engineering-oriented introduction to wave propagation that focuses on wave propagation in one-dimensional models that are anchored by the classical wave equation. The text is written in a style that is highly accessible to undergraduates, featuring extended and repetitive expositions and displaying and explaining mathematical and physical details—many classical but others not heretofore published. The formulations are devised to provide analytical foundations for studying more ad

Book SynopsisIn the tradition of Daniel Levitin's This Is Your Brain on Music and Oliver Sacks' Musicophilia, Bad Singer follows the delightful journey of Tim Falconer as he tries to overcome tone deafness and along the way discovers what we're really hearing when we listen to music.Tim Falconer, a self-confessed bad singer, always wanted to make music, but soon after he starts singing lessons, he discovers that he's part of only 2.5 percent of the population afflicted with amusia in other words, he is scientifically tone-deaf. Bad Singer chronicles his quest to understand human evolution and music, the brain science behind tone-deafness, his search for ways to retrain the adult brain, and his investigation into what we really hear when we listen to music. In an effort to learn more about his brain disorder, he goes to a series of labs where the scientists who test him are as fascinated with him as he is with them. He also sets out to Trade ReviewA remarkable story of dogged determination to prove his own body wrong and, as such, is one of the more illuminating cultural studies of modern times. * Globe and Mail *Falconer is old school in his traditional approach to journalism. He conducts lengthy interviews and fluidly articulates complex scientific concepts. He’s the protagonist yet he doesn’t digress into self-indulgence. The result is fresh, intelligent prose. While he may be a bad singer, he’s a thorough researcher and gifted raconteur. What Falconer lacks in pitch he makes up for in curiosity and passion. * Toronto Star *An engaging, step-by-step look into how scientists study tone deafness . . . an essential tale about how human beings, even those of us with tin ears, can’t help but be drawn to music . . . Over the last decade there have been a number of books published about the science of music — such as Daniel Levitan’s This Is Your Brain on Music, Oliver Sacks’s Musicophilia, and David Byrne’s How Music Works — and Bad Singer is a doubly successful effort because it doesn’t retread the same ground of these books, with Falconer couching his subject in a personal journey that’s enjoyable to follow. * National Post *Bad Singer deftly combines a memoir of Falconer’s personal musical history with a scientific look into how humans hear music. * Maclean's *A spirited, even adventurous look at the mysteries of how the human brain perceives and processes sound — and even, on occasion, manages to make beautiful music. * Kirkus Reviews *Falconer’s self-deprecating humour keeps Bad Singer’s tone lighthearted and as entertaining as the photos of him hamming it up as a singer on the book cover. Lines like ‘I’m a bad singer. And deep down, it matters’ produce an undercurrent of sorrow, but far more pronounced are his curiosity, vulnerability, and perseverance. It’s a deeply human book, and his most personal. * Quill & Quire *An engaging tale. * Winnipeg Free Press *

Book SynopsisWhat is everything made of? How do things change and how do they work? What is life? In The Nature of Nature, visionary scientist Irv Dardik tackles these questions by introducing his discovery of SuperWaves, a singular wave phenomenon whose design generates what we experience as matter, space, time, motion, energy, and order and chaos. Simply put, the SuperWaves principle states that the fundamental stuff of nature is waves—waves waving within waves, to be exact. Dardik challenges the rationality of accepting a priori that the universe is made of discrete particles. Instead, by drawing from his own discovery of a unique wave behavior and combining it with scientific facts, he shows that every single thing in existence—from quantum particles to entire galaxies—is waves waving in the unique pattern he calls SuperWaves. The discovery of SuperWaves and the ideas behind it, while profound, can be intuitively grasped by every reader, whether scientist or layperson. Touching on everything from quantum physics to gravity, to emergent complexity and thermodynamics, to the origins of health and disease, it shows that our health, and the health of the environment and civilization, depend upon our understanding SuperWaves. The Nature of Nature is an absorbing account that combines Dardik’s contrarian look at the history of science with philosophical discussion, his own groundbreaking research, and hope for the future.
